2009年8月25日 · Triphenylphosphine (PPh 3)-capped 1.8 nm diameter gold nanoparticles (AuNPs) are characterized by a combination of 1 H, 2 H, and 31 P solution- and solid-state NMR. The 31 P{1 H} NMR resonance associated with the surface-bound PPh 3 is clearly identified and is present as a broad peak centered at 56 ppm.

1996年6月1日 · In contrast, the solid state "P NMR analysis of copper(l) complexes allows to assign CN three because of the lower symmetry relative to CN four. '2" The values for 1-4 are in good agreement with the resonances of [Cu(PPh3)2] [N03] (0.3 ppm), [Cu(PPh3)3][NO3] (-2.9 ppm) and [Cu(PPh3)4][C104] (-5.0 ppm)."

A: PPH3 NMR, or triphenylphosphine (PPh3) nuclear magnetic resonance spectroscopy, is a powerful analytical technique used to characterize and quantify triphenylphosphine (PPh3) in various samples. PPh3, a common organophosphorus compound, serves as a crucial ligand in numerous organometallic reactions, homogeneous catalysis, and material ...
